BOV and Vac

Does a BOV need vacuum? I was informed it runs off pressure. But if someone can correct me on this.

Re:BOV and Vac

the vacuum created inside the intake manifold when you close the throttle plate will "suck" the bov open to release the pressure from the turbo

Re:BOV and Vac

Because I have my bov ran off a barb in my charge pipes next to my throttle body. Wondering if I should move this to the brake booster line.

Re:BOV and Vac

there should be one going from your intake manifold to the fuel pressure regulator or something similar which would be the best one to use

I always heard for BOV that brake booster was the best?

Re:BOV and Vac

i've never heard of using the brake booster vacuum, but i guess it's all the same... on my 89 supra turbo the bov is actuated by a vacuum line coming from the intake manifold, if anything, i would say this would allow for the quickest bov actuation
